    Electric potential inside a conducting sphere

    A) is zero

    B) remains constant

    C) decreases from centre to surface.

    D) increases from centre to surface.

    Correct Answer: B

    Solution :

    Option [b] is correct.
    Explanation: Inside the sphere, E = 0
    Again E = - dV/dr
    So, dV/dr = 0
    This is possible when V is constant.
